The Austrian Danube River Information Services - DoRIS have been operational since 2006 (www.doris.bmvit.gv.at). The infrastructure and the deployed technologies (operating system, data management, central servers, landside base stations, etc.) for one of the main functions of DoRIS, the support of traffic information on the basis of the Inland-AIS standards, are accordingly outdated. In order to continuously ensure the reliable and future-proof operation of these functions,viadonau is steadily working on the gradual renewal of relevant system elements.
In the first half of 2017, the bandwidths of the 23 DoRIS base stations along the Danube were increased and the central firewall was replaced by a new, state-of-the-art, redundant firewall, in order to comply with the increased current and future data transfer requirements.
For the renewal of the central DoRIS AIS infrastructure a specification was elaborated in spring 2018 which provided the basis for a Europe-wide, two-stage tender procedure. In November 2018 the best bidder of this tender procedure was commissioned with the implementation of the renewal of central DoRIS components, which should take place in the third quarter of 2019. In the framework of this renewal well-established functionalities will be maintained and improved, and new functionalities, such as the broadcasting of the vertical bridge clearance or the real-time positioning of buoys via AIS, will be implemented. Furthermore, the integrability of the services developed in the context of the RIS COMEX Project and the interfaces with central European systems should be ensured.
In order to guarantee continuous availability of the current system until the final migration to the new system, the central physical servers of the source system were virtualised in 2018.
